［摘要］以樂山奧林匹克中心項(xiàng)目游泳館比賽區(qū)屋蓋為實(shí)例，采用3D3S及MIDAS Gen軟件對56.7m跨度的張弦膠合木拱架結(jié)構(gòu)在結(jié)構(gòu)受力、結(jié)構(gòu)變形及空間穩(wěn)定等方面進(jìn)行研究，并對膠合木結(jié)構(gòu)半剛性拼接節(jié)點(diǎn)、膠合木結(jié)構(gòu)防火設(shè)計(jì)等方面進(jìn)行分析。研究結(jié)果表明，張弦膠合木拱架結(jié)構(gòu)能充分發(fā)揮預(yù)應(yīng)力拉索和膠合木結(jié)構(gòu)各自的優(yōu)點(diǎn)，具有優(yōu)越的力學(xué)性能，能夠較好地應(yīng)用于大跨度空間結(jié)構(gòu)中。

Abstract:Taking the roof of the swimming pool competition area of the Leshan Olympic Center project as an example, 3D3S and MIDAS Gen software were used to study the structural force, structural deformation and spatial stability of the 56.7m span glulam arch structure, and the semi-rigid splicing joints of the glulam structure and the fire protection design of the glulam structure were analyzed. The results show that tension string glulam arch structure can take full advantage of pre-stressed steel cable and the glulam structure, and has extraordinary mechanical property, which can be better used in large-span space structures.
Keywords:Leshan Olympic Center; tension string glulam arch structure; structural stability; semi-rigid joint; wood structure; fire protection design
